Modularization of the UML Metamodel Using Model Slicing

The UML metamodel has been increased in its size and complexity due to many needs for supporting various platforms and domains. The large size of the metamodel can prevent tool developers from understanding the UML metamodel and thus from developing UML-based tools. In this paper, we propose an approach to managing the complexity of the UML metamodel by modularizing the metamodel into a set of small metamodels for each UML diagram type. To that goal, we propose a slicing algorithm for extracting diagram-specific metamodels from the UML metamodel.
